How to present iOS UIActionSheet in Swift?

Updated for Swift 4/5

Works for iOS 11-14

Some of the other answers are okay but I ended up mixing and matching a few of them to rather come up with this :

@IBAction func showAlert(sender: AnyObject) {
    let alert = UIAlertController(title: "Title", message: "Please Select an Option", preferredStyle: .actionSheet)
    
    alert.addAction(UIAlertAction(title: "Approve", style: .default , handler:{ (UIAlertAction)in
        print("User click Approve button")
    }))
    
    alert.addAction(UIAlertAction(title: "Edit", style: .default , handler:{ (UIAlertAction)in
        print("User click Edit button")
    }))

    alert.addAction(UIAlertAction(title: "Delete", style: .destructive , handler:{ (UIAlertAction)in
        print("User click Delete button")
    }))
    
    alert.addAction(UIAlertAction(title: "Dismiss", style: .cancel, handler:{ (UIAlertAction)in
        print("User click Dismiss button")
    }))

    
    //uncomment for iPad Support
    //alert.popoverPresentationController?.sourceView = self.view

    self.present(alert, animated: true, completion: {
        print("completion block")
    })
}

Enjoy 🙂
